plugin.

check_by_ssh uses the spopen() function to call ssh. The spopen()
function is designed for nagios plugins.  However, one side-effect of
spopen() is that it wipes out the environment before executing the
program.  And ssh-agent passes on info to the ssh command through use of
the environment.

You may want to consider looking into hostbased ssh authentication,
depending on how your network setup is.
